Answer:
C) 50
Step-by-step explanation:
You first look at the 40 given to you. Then you know the angle opposite of it will be 40 also because of the law that opposite angles are the same. Once you have two angles in the triangle you can add 40 plus 90 in which you get 130 but that does not equal 180. So you can see that angle 1 is 50 because 50 and 130 equals 180.
First we find X:
3x+x=180
4x=180
x=180/4
x=45.
3x=135
135+y=180
y=180-135
y=45
45+z=180
z=180-45
z=135
In conclusion, x=45, 3x=135, y=45 and z =135
Also note that the opposite angles are equal so you can just find 3x and that will be equal to z and x will be equal to y.
